Tools for builders
Free tools for Minecraft files. Everything runs in your browser — files are never uploaded.
Version encyclopedia
Every Java block and item since 1.14: render, textures, names and change history.
File detector
Drop a .schem, .litematic, .bp, .nbt, .schematic, level.dat or a world archive — see the format, game version, size and block palette.
OpenViewer
3D view of schematics and blueprints right in the browser, with textures from the encyclopedia.
OpenConverter
Between formats and versions — with a preview of every replacement and no state "normalisation".
Editor
Crop, replace blocks, tweak NBT and get a world ready for hand-off.
